Abstract
Description
Technical Field
[0001] The utility model relates to a zipper. Background Art
[0002] A zipper is a connecting piece that relies on continuously arranged chain teeth to realize the combination or separation of items, and is widely used in items such as clothing, bags, tents, etc. Generally, a zipper includes a pair of left and right cloth tapes, a row of chain teeth fixed on the inner edge of each cloth tape, and a slider that engages with the row of chain teeth. The row of chain teeth includes a plurality of chain teeth arranged side by side in the front-back direction along the length of the zipper. Pulling the slider forward or backward along the length of the zipper causes a pair of rows of chain teeth to engage or separate, thereby closing or opening the zipper accordingly.
[0003] In some existing zippers, a separation insert is provided at one end of the row of chain teeth. The separation insert mainly includes an insert body and a pivot support body. The insert body is continuously formed at the end of the row of chain teeth of one of the pair of left and right cloth tapes, and the pivot support body is continuously formed at the end of the row of chain teeth of the other of the pair of cloth tapes. Along the width direction of the zipper, the insert body is inserted and fixed from the side of the pivot support body, but along the length direction of the zipper, the insert body does not pass through the chain tooth guiding passage in the slider, thereby causing a pair of left and right rows of chain teeth to engage. For example: A zipper disclosed in the Chinese invention patent application with the application number 200980147733.5. Therefore, the slider and the pivot support body are assembled on the same cloth tape, and the insert body is assembled on the other cloth tape.
[0004] Furthermore, in some zippers equipped with separation inserts, the insert body and the pivot support body are in a rotational fit. When the zipper needs to be opened: Pull the slider to the end of the row of chain teeth and abut it against the pivot support body, rotate the insert body and the pivot support body in a direction away from each other to release the engagement between the insert body and the pivot support body, and the zipper can be opened. When the zipper needs to be closed: Rotate the insert body and the pivot support body in a direction towards each other until they are engaged, and pull the slider in a direction away from the pivot support body, and the zipper can be closed.
[0005] However, the above-mentioned zipper equipped with a separation insert has a problem of idling in actual use. Specifically: After the zipper is used on clothes, when the user pulls the slider to close the zipper, if the user pulls up the slider in the direction of releasing the engagement, it will drive the pivot support body to rotate in a direction away from the insert body, and this rotation direction is the rotation direction when the engagement is released. As a result, it is very easy for the already engaged insert body and pivot support body to be separated again, resulting in idling (i.e., the ineffective rotation of the insert body and / or the pivot support body), and the slider pulling empty (i.e., the slider is only pulled along the row of chain teeth on its own side in the state where the separation insert is separated), causing the operation of closing the zipper to fail and reducing the user experience of the zipper. Summary of the Utility Model
[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a zipper that can avoid the idling phenomenon when the zipper is closed.
[0007] To achieve the above object, the present utility model provides a zipper, which includes a separable first zipper component and a second zipper component.
[0008] The first zipper component includes a first cloth tape, a first row of chain teeth fixed on the inner edge of the first cloth tape, a slider movably mounted on the first row of chain teeth along the length direction of the zipper, and a seat rod component fixed on the inner edge of the first cloth tape and distributed at the end of the first row of chain teeth; the slider includes an upper wing plate and a lower wing plate oppositely arranged and connected in the thickness direction of the zipper, and the upper wing plate and the lower wing plate are respectively provided with an upward protruding flange portion and a downward protruding flange portion; the seat rod component includes a seat rod main body portion and a seat rod arm portion extending from the seat rod main body portion toward the first row of chain teeth.
[0009] The second zipper component includes a second cloth tape, a second row of chain teeth fixed on the inner edge of the second cloth tape, and an inserting rod component fixed on the inner edge of the second cloth tape and distributed at the end of the second row of chain teeth; the inserting rod component includes an inserting rod main body portion, an inserting rod arm portion extending from the inserting rod main body portion toward the second row of chain teeth, and a half row of chain teeth fixed to the inserting rod main body portion and adjacent to the second row of chain teeth.
[0010] The seat rod component and the inserting rod component are rotationally matched and separable; when the seat rod component and the inserting rod component are combined, the seat rod main body portion, the seat rod arm portion and the inserting rod arm portion enclose a slider accommodating area capable of accommodating the slider.
[0011] On the side surface of the seat rod arm portion facing the slider accommodating area, there is an inclined protrusion protruding toward the slider accommodating area; a flange channel is formed between the half row of chain teeth and the inserting rod arm portion, and the flange channel is a part of the slider accommodating area and is for the upward flange portion and the downward flange portion on the side of the slider close to the inserting rod arm portion to pass through.
[0012] When the seat rod component and the inserting rod component are combined, and the slider is located in the slider accommodating area and abuts against the seat rod main body portion, the inclined protrusion abuts against the outer peripheral side of the slider and drives the slider to incline toward the inserting rod component.
[0013] In the above zipper, when it is necessary to close the zipper, first pull the slider to the end of the first row of teeth on the first zipper component, then the slider abuts against the seat rod component. After that, engage the plug rod component on the second zipper component with the seat rod component on the first zipper component, and then the plug rod component and the seat rod component rotate towards each other until they are combined; at this time, the seat rod main body, the seat rod arm and the plug rod arm enclose a slider accommodating area, and the slider is exactly located in this slider accommodating area; moreover, along the width direction of the zipper, the seat rod arm and the plug rod arm are distributed on both sides of the slider, and the inclined protrusion on the seat rod arm abuts against the outer peripheral side of the slider, thereby driving the slider to tilt towards the plug rod component. Then, the user pulls the slider, driving the slider to move along the length direction of the zipper away from the plug rod component and the seat rod component, that is, driving the slider to move out of the slider accommodating area, driving the first row of teeth and the second row of teeth to mesh, and the slider engaged with the first row of teeth and the second row of teeth returns to a straight and non-tilted state. Therefore, during the process of pulling the slider out of the slider accommodating area, the upper flange part and the lower flange part on the side of the slider close to the plug rod arm pass through the flange channel of the plug rod component, and the slider switches from the tilted state towards the plug rod component to the non-tilted state, thus realizing the rotation of the plug rod component towards the seat rod component induced by the slider during this process. This rotation direction is the combination direction, even if the slider is pulled up along the combination release direction, the combination will not come off, effectively avoiding the idle rotation of the plug rod component or the seat rod component in the combination release direction, ensuring the reliable combination of the plug rod component and the seat rod component when closing the zipper, reliably guaranteeing the success rate of the zipper closing operation, and improving the user experience of the zipper.
[0014] Further, a recessed portion recessed away from the flange channel is provided on the outer periphery of one end of the half chain tooth away from the second chain tooth row, and the recessed portion communicates with the flange channel; when the seat rod member and the insertion rod member are combined, and the slider is located in the slider accommodating area and abuts against the main body portion of the seat rod, the upper flange portion and / or the lower flange portion and the recessed portion are distributed in sequence along the moving direction of the slider when the zipper is closed, and the end of the upper flange portion and / or the lower flange portion can abut against the recessed portion. During the process of pulling the slider out of the slider accommodating area, the upper flange portion and the lower flange portion on the slider may collide with the half chain tooth. When the ends of the upper flange portion and the lower flange portion collide with the half chain tooth, the ends of the upper flange portion and / or the lower flange portion abut in the recessed portion of the half chain tooth, and the outer peripheral contour of the recessed portion recessed away from the flange channel surrounds the outer periphery of the ends of the upper flange portion and / or the lower flange portion, and the recessed portion receives the ends of the upper flange portion and / or the lower flange portion; on the one hand, it restricts the rotation of the half chain tooth in the direction of disengagement of the combination, so as to achieve the purpose of restricting the rotation of the insertion rod member in the direction of disengagement of the combination; on the other hand, when the upper flange portion and the lower flange portion pass through the outer periphery of the half chain tooth, it will drive the half chain tooth to rotate towards the seat rod member, that is, it will drive the insertion rod member to rotate towards the seat rod member. Therefore, the setting of the recessed portion makes it difficult for the insertion rod member to rotate in the direction of disengagement of the combination, effectively avoids the idling of the insertion rod member, and better improves the combination reliability of the insertion rod member and the seat rod member.
[0015] Further, the recessed portion is provided on both the front and back surfaces of the half chain tooth. The front recessed portion of the half chain tooth can abut against the end of the upper flange portion, and the back recessed portion of the half chain tooth can abut against the end of the lower flange portion, which better restricts the idling of the insertion rod member towards the disengagement side.
[0016] Further, the outer peripheral contour of the recessed portion includes a plurality of recessed inclined surfaces, and the plurality of recessed inclined surfaces are connected in sequence along the length direction of the zipper, so that the recessed portion receives the ends of the upper flange portion and / or the lower flange portion with a surface, which better restricts the rotation of the insertion rod member in the direction of disengagement of the combination.
[0017] Further, the inclination angles of the plurality of recessed inclined surfaces are different. Specifically, the slopes of the plurality of recessed inclined surfaces relative to the central axis extending along the length direction of the zipper gradually increase. In this way, when the ends of the upper flange portion and the lower flange portion collide with the half chain tooth, the first recessed inclined surface can accommodate the ends of the upper flange portion and / or the lower flange portion, so that the half chain tooth will not idle; due to the increase in the slope, the remaining recessed inclined surfaces are distributed on one side of the upper flange portion and / or the lower flange portion along the moving direction of the slider when the zipper is closed. In this way, the user needs to apply a certain force to the slider to make the upper flange portion and / or the lower flange portion pass through the outer peripheral side of the half chain tooth after crossing the remaining recessed inclined surfaces. Due to the application of this force, it better drives the insertion rod member to rotate towards the seat rod member, so that the insertion rod member and the seat rod member are better combined.
[0018] Preferably, there are three concave inclined surfaces, which are respectively a first inclined surface, a second inclined surface and a third inclined surface connected in sequence along the length direction of the zipper. An arc section is connected between the first inclined surface and the outer peripheral surface of the half chain tooth, and between the third inclined surface and the outer peripheral surface of the half chain tooth.
[0019] Further, when the seat rod component and the insertion rod component are combined, and the slider is located in the slider accommodation area and abuts against the main body part of the seat rod, the inclination angle α of the inclined protrusion driving the slider to incline towards the insertion rod component is 20°-25°, and particularly preferably 22°. In this way, at the beginning of the combination of the seat rod component and the insertion rod component, it can be avoided that the slider inclines excessively towards the insertion rod component, thereby avoiding that the insertion rod component is too far away from the seat rod component, and ensuring that the subsequent insertion rod component and the seat rod component can be better combined.
[0020] Further, when the seat rod component and the insertion rod component are combined, and the slider is located in the slider accommodation area and abuts against the main body part of the seat rod, a gap is formed between the part of the seat rod arm except the inclined protrusion and the slider. The setting of this gap makes it easy for the slider to be pulled into the slider accommodation area at the ends of the first row of teeth and the second row of teeth when opening the zipper; and when closing the zipper, the slider can be easily pulled out from the slider accommodation area.
[0021] Further, the seat rod component further includes a first magnet fixed in the main body part of the seat rod, and the insertion rod component further includes a second magnet fixed in the main body part of the insertion rod. A magnetic adsorption force that makes the seat rod component and the insertion rod component rotate towards each other can be generated between the first magnet and the second magnet, which is more convenient for the rotational combination of the seat rod component and the insertion rod component and improves the use experience.
[0022] Further, a reinforcing rib is fixedly arranged on the surface of the upper wing plate close to the insertion rod component to improve the structural strength of the upper wing plate.
[0023] As described above, the zipper involved in the present utility model has the following beneficial effects:
[0024] In the process of pulling the slider out of the slider accommodation area in this application, the upper flange part and the lower flange part on the side of the slider close to the insertion rod arm pass through the flange channel of the insertion rod component, and the slider switches from the inclined state towards the insertion rod component to the non-inclined state, realizing that the slider induces the insertion rod component to rotate towards the seat rod component during this process. This rotation direction is the combination direction, that is, even if the slider is pulled up along the combination release direction, the combination will not come off, effectively avoiding the idling of the insertion rod component or the seat rod component in the combination release direction, ensuring the reliable combination of the insertion rod component and the seat rod component when closing the zipper, reliably guaranteeing the success rate of the zipper closing operation, and improving the use experience of the zipper.

[0084] Such as Figure 1As shown, the present application provides a zipper, which has a slider 30. For the convenience of description, in the following embodiments, the definitions of each direction are as follows: the length direction of the zipper is defined as the front-back direction, the width direction of the zipper is defined as the left-right direction, and the thickness direction of the zipper is defined as the up-down direction; and, the front direction is the moving direction of the slider 30 when the zipper is closed, and the back direction is the moving direction of the slider 30 when the zipper is opened. Based on this, Figure 1 In the view shown, the upper side and the lower side of the paper surface are the front direction and the back direction respectively, the left side and the right side of the paper surface are the left direction and the right direction respectively, and the front side and the back side of the paper surface are the up direction and the down direction respectively.
[0085] As Figures 1 to 4 shown, the zipper involved in the present application includes a separable first zipper component 100 and a second zipper component 200. The first zipper component 100 is distributed on the left side, and the second zipper component 200 is distributed on the right side.
[0086] As Figure 3 and Figure 4 shown, the first zipper component 100 includes a first tape 10, a first row of teeth 20 fixedly arranged on the right inner edge of the first tape 10, a slider 30 movably mounted on the first row of teeth 20 along the length direction of the zipper, and a seat bar component 40 fixedly arranged on the right inner edge of the first tape 10. The first row of teeth 20 includes a plurality of teeth arranged side by side in the front-back direction along the length direction of the zipper. The seat bar component 40 is distributed at the end of the first row of teeth 20, that is, at the rear end, along the length direction of the first row of teeth 20. As Figure 10 and Figure 11 shown, the slider 30 includes an upper wing plate 31 and a lower wing plate 32 which are oppositely arranged up and down and connected along the thickness direction of the zipper, a connecting column part 36 connected between the upper wing plate 31 and the lower wing plate 32, a mounting column part 37 fixed on the upper surface of the upper wing plate 31, and a pull tab 38 rotatably mounted on the mounting column part 37. The user can conveniently pull the slider 30 forward or backward by holding the pull tab 38. At the same time, upper flange parts 33 protruding downward are provided at the left and right edges of the upper wing plate 31, and lower flange parts 34 protruding upward are provided at the left and right edges of the lower wing plate 32. Then, the upper flange parts 33 and the lower flange parts 34 protrude towards each other in the up-down direction. A tooth guiding passage 39 penetrating through the front and back is formed between the upper wing plate 31, the lower wing plate 32 and the connecting column part 36 of the slider 30. The front end opening of the tooth guiding passage 39 is the shoulder opening of the slider 30; and, the connecting column part 36 is arranged at the front end side of the upper wing plate 31 and the lower wing plate 32. The tooth guiding passage 39 penetrates through the area between the upper wing plate 31 and the lower wing plate 32 in the left-right direction and is distributed at the rear side of the connecting column part 36, that is, the rear side of the connecting column part 36 is an empty area for the seat bar component 40 to be combined with the plug bar component 70 described later. As Figures 7 to 9As shown, the seat rod member 40 includes a seat rod main body portion 41 and a seat rod arm portion 42 extending forward from the left side of the seat rod main body portion 41 toward the first row of chain teeth 20; along the width direction of the zipper, the seat rod arm portion 42 is distributed on the left side of the first row of chain teeth 20, or rather, the seat rod arm portion 42 is arranged on the outer side relative to the first row of chain teeth 20.
[0087] As Figure 3 and Figure 4 shown, the second zipper member 200 includes a second fabric tape 50, a second row of chain teeth 60 fixed to the inner edge on the left side of the second fabric tape 50, and an insertion rod member 70 fixed to the inner edge on the left side of the second fabric tape 50. The second row of chain teeth 60 also includes a plurality of chain teeth arranged side by side in the front-back direction along the length of the zipper. The insertion rod member 70 is distributed at the end, i.e., the rear end, of the second row of chain teeth 60 along the length direction of the second row of chain teeth 60. As Figures 12 to 14 shown, the insertion rod member 70 includes an insertion rod main body portion 71, an insertion rod arm portion 72 extending forward from the right side of the insertion rod main body portion 71 toward the second row of chain teeth 60, and a half chain tooth 73 fixed to the insertion rod main body portion 71 and adjacent to the second row of chain teeth 60. Along the width direction of the zipper, the insertion rod arm portion 72 is distributed on the right side of the second row of chain teeth 60, or rather, the insertion rod arm portion 72 is arranged on the outer side relative to the second row of chain teeth 60. The half chain tooth 73 is distributed at the front end of the insertion rod member 70. At the same time, the half chain tooth 73 is distributed behind the last chain tooth in the second row of chain teeth 60, and a flange channel 74 is formed between the half chain tooth 73 and the insertion rod arm portion 72.
[0088] In the above zipper, the seat rod member 40 and the insertion rod member 70 form a separable insertion member of the zipper, and the seat rod member 40 is rotationally engaged with the insertion rod member 70 and can be separated and combined. Figure 1 When the zipper shown is in the closed state, the chain teeth in the first row of chain teeth 20 and the chain teeth in the second row of chain teeth 60 are engaged, and the seat rod member 40 and the insertion rod member 70 are combined. At this time, the seat rod main body portion 41, the seat rod arm portion 42, and the insertion rod arm portion 72 enclose a slider accommodating area 80, and the slider accommodating area 80 can accommodate the slider 30. The flange channel 74 of the insertion rod member 70 is a part of the slider accommodating area 80.
[0089] When it is necessary to open Figure 1 the zipper shown, the user pulls the slider 30 backward by holding the pull tab 38 until the slider 30 is pulled backward to a state of abutting against the seat rod member 40. As Figure 3As shown, at this time, the slider 30 is located in the slider accommodation area 80; and during this process, the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30 pass backward through the flange channel 74 of the plug member 70. After that, the seat rod member 40 and the plug member 70 are rotated away from each other. When the plug member 70 is removed from the tooth guiding path 39 of the slider 30, the seat rod member 40 and the plug member 70 can be separated up and down, separating the zipper into the first zipper member 100 and the second zipper member 200, as Figure 4 shown.
[0090] When it is necessary to close the Figure 4 zipper shown, first, the seat rod member 40 and the plug member 70 are brought into abutment up and down, and the slider 30 is pulled backward to a position where it abuts against the seat rod member 40. Then, the seat rod member 40 and the plug member 70 are rotated towards each other until the left end portion of the plug member 70 enters the tooth guiding path 39 of the slider 30 from the right side of the slider 30, then the seat rod member 40 and the plug member 70 are combined, as Figure 3 shown. At this time, the slider 30 is located in the slider accommodation area 80. After that, the user pulls the slider 30 forward by holding the pull tab 38, then the slider 30 is pulled out forward from the slider accommodation area 80, and the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30 pass forward through the flange channel 74 of the plug member 70. As the slider 30 moves forward, the teeth of the first row of teeth 20 passing through the tooth guiding path 39 of the slider 30 mesh with the teeth of the second row of teeth 60, and the half teeth 73 are distributed behind the rearmost teeth in the first row of teeth 20 and the two are engaged, as Figure 1 shown.
[0091] Therefore, in the above zipper, the rightward rotation of the seat rod member 40 and the leftward rotation of the plug member 70 are the combination directions, and the leftward rotation of the seat rod member 40 and the rightward rotation of the plug member 70 are the combination release directions.
[0092] In particular, as Figure 7 and Figure 9 shown, an inclined protrusion 421 protruding rightward toward the slider accommodation area 80 is provided on the right side surface of the seat rod arm portion 42 facing the slider accommodation area 80. When the seat rod member 40 and the plug member 70 are combined, and the slider 30 is located in the slider accommodation area 80 and abuts against the seat rod main body portion 41, as Figure 3 , Figure 5 and Figure 6 shown, the inclined protrusion 421 abuts against the outer peripheral side on the left side of the slider 30. Under the action of the abutment of the inclined protrusion 421, the whole slider 30 is driven to incline toward the plug member 70, that is, the slider 30 inclines to the right, and then the shoulder opening of the slider 30 also inclines to the right. The rightward inclination of the slider 30 means: as Figure 3As shown, the seat bar member 40 has a first central axis S extending along its length direction. The first central axis S extends back and forth and is the central axis extending along the length direction of the zipper. The slider 30 has a second central axis W extending along its length direction. The second central axis W of the slider 30 is inclined to the right with respect to the first central axis S of the seat bar member 40, and there is an acute angle α between the second central axis W and the first central axis S. This acute angle α is also the inclination angle of the slider 30 inclined to the right towards the insertion bar member 70. This structural setting has the following advantages.
[0093] When the zipper needs to be closed, first pull the slider 30 to the end of the first row of teeth 20 on the first zipper member 100, then the slider 30 abuts against the seat bar member 40. Then, the insertion bar member 70 and the seat bar member 40 rotate towards each other to achieve their combination, as Figure 3 and Figure 5 shown; at this time, the seat bar arm portion 42 and the insertion bar arm portion 72 are respectively distributed on the left and right sides of the slider 30, and the slider 30 is exactly located in the slider accommodation area 80, and the slider 30 is inclined to the right towards the insertion bar member 70. When the user pulls the slider 30 forward by holding the pull tab 38 and pulls the slider 30 out of the slider accommodation area 80 forward, as Figure 1 shown, the first row of teeth 20 and the second row of teeth 60 of the slider 30 are engaged, and the slider 30 that bites on the first row of teeth 20 and the second row of teeth 60 returns to a straight and non-inclined state, that is, at this time, the second central axis W of the slider 30 is parallel to the first central axis S of the seat bar member 40 and both extend straight back and forth. Therefore, in the process of pulling the slider 30 out of the slider accommodation area 80 forward, the slider 30 switches from the inclined state towards the insertion bar member 70 to the non-inclined state, that is, the slider 30 turns to the left by an angle towards the seat bar member 40. Combining the fact that the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30 pass through the flange channel 74 of the insertion bar member 70 during this process, thereby realizing that the slider 30 induces the insertion bar member 70 to turn to the left towards the seat bar member 40 during this process. The rotation direction of the insertion bar member 70 turning to the left is the combination direction, so that the insertion bar member 70 and the seat bar member 40 are reliably combined. In this way, even when the slider 30 is pulled up along the combination release direction when closing the zipper, the combination of the insertion bar member 70 and the seat bar member 40 will not come off, effectively avoiding the idling of the insertion bar member 70 or the seat bar member 40 in the direction of combination release, ensuring the reliable combination of the insertion bar member 70 and the seat bar member 40 when closing the zipper, reliably guaranteeing the success rate of the zipper closing operation, and improving the user experience of the zipper.
[0094] Furthermore, as Figure 3 、 Figure 5 and Figure 6As shown, when the seat rod component 40 and the inserting rod component 70 are combined, and the slider 30 is located in the slider accommodating area 80 and abuts against the seat rod main body 41, the inclination angle α at which the inclined protrusion 421 drives the slider 30 to incline towards the inserting rod component 70 is 20° to 25°, and preferably 22°. In this way, at the beginning of the combination of the seat rod component 40 and the inserting rod component 70, it is possible to prevent the slider 30 from excessively inclining to the right towards the inserting rod component 70, thereby preventing the inserting rod component 70 from excessively moving away from the seat rod component 40, and ensuring better combination of the subsequent inserting rod component 70 and the seat rod component 40. In addition, as Figure 7 shown, the inclined protrusion 421 on the right side surface of the seat rod arm 42 is triangular. When it abuts against the left outer peripheral surface of the slider 30, it can not only drive the slider 30 to incline to the right, but also make the contact area between the inclined protrusion 421 and the slider 30 smaller, reduce the friction force between the two, and facilitate the forward pulling out of the slider 30 from the slider accommodating area 80 and the backward pulling of the slider 30 into the slider accommodating area 80.
[0095] Furthermore, as Figure 3 and Figure 5 shown, when the seat rod component 40 and the inserting rod component 70 are combined, and the slider 30 is located in the slider accommodating area 80 and abuts against the seat rod main body 41, a gap 43 is formed between the part of the seat rod arm 42 other than the inclined protrusion 421 and the slider 30. The gap 43 penetrates up and down, and the gap 43 exists on both the upper side and the lower side of the inclined protrusion 421. The setting of the gap 43 greatly reduces the contact area between the seat rod arm 42 and the slider 30, and also greatly reduces the friction force between the two. In this way, when opening the zipper, the slider 30 can be easily pulled backward into the slider accommodating area 80 at the rear ends of the first row of teeth 20 and the second row of teeth 60; and when closing the zipper, the slider 30 can also be easily pulled forward out of the slider accommodating area 80.
[0096] Furthermore, as Figures 12 to 15 shown, a recess 731 that is recessed away from the flange channel 74 is provided on the outer periphery of the half tooth 73 away from the right rear end of the second row of teeth 60. Then the recess 731 is formed on the outer peripheral side of the right rear end of the half tooth 73, so the recess 731 communicates with the flange channel 74. When the seat rod component 40 and the inserting rod component 70 are combined, and the slider 30 is located in the slider accommodating area 80 and abuts against the seat rod main body 41, as Figure 5 shown, the upper flange part 33 and / or the lower flange part 34 on the right side of the slider 30 and the recess 731 are distributed in sequence along the moving direction of the slider 30 when the zipper is closed, that is, the upper flange part 33 and / or the lower flange part 34 on the right side of the slider 30 are distributed at the rear side of the recess 731.
[0097] In the process of closing the zipper by pulling the slider 30 forward from the slider accommodating area 80, the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30 may directly pass forward from the flange channel 74 on the outer peripheral side of the half slider teeth 73 without colliding with the half slider teeth 73; alternatively, the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30 may first collide with the half slider teeth 73 and then pass forward from the flange channel 74. When the front end portions of the upper flange portion 33 and the lower flange portion 34 collide with the half slider teeth 73, the front end portions of the upper flange portion 33 and / or the lower flange portion 34 will abut against the recessed portion 731 at the right rear end of the half slider teeth 73. The outer peripheral contour of the recessed portion 731 that recesses away from the flange channel 74 surrounds the outer periphery of the front end portions of the upper flange portion 33 and / or the lower flange portion 34. The recessed portion 731 receives the front end portions of the upper flange portion 33 and / or the lower flange portion 34, and this structure has the following functions. On the one hand, since the front end portions of the upper flange portion 33 and / or the lower flange portion 34 abut against the recessed portion 731 at the right rear end of the half slider teeth 73, it will limit the right rotation of the half slider teeth 73 in the direction of disengagement, that is, it achieves the purpose of restricting the right rotation of the plug member 70 in the direction of disengagement; on the other hand, when a force is subsequently applied to the slider 30 to pass the upper flange portion 33 and / or the lower flange portion 34 through the outer periphery of the half slider teeth 73, the upper flange portion 33 and / or the lower flange portion 34 will drive the half slider teeth 73 to rotate leftward toward the seat rod member 40, that is, further induce the plug member 70 to rotate leftward toward the seat rod member 40. Therefore, the setting of the recessed portion 731 makes it difficult for the plug member 70 to rotate in the direction of disengagement, effectively avoiding the idling of the plug member 70 and better improving the bonding reliability between the plug member 70 and the seat rod member 40.
[0098] Furthermore, the arrangement of the recessed portion 731 on the half slider teeth 73 can be as follows: The recessed portion 731 is provided only on the front surface (i.e., the upper surface) of the half slider teeth 73, then the recessed portion 731 only receives the front end portion of the upper flange portion 33 on the right side of the slider 30; or, the recessed portion 731 is provided only on the back surface (i.e., the lower surface) of the half slider teeth 73, then the recessed portion 731 only receives the front end portion of the lower flange portion 34 on the right side of the slider 30; or, the front surface and the back surface of the half slider teeth 73 are both provided with the recessed portion 731, then the upper and lower recessed portions 731 respectively receive the front end portions of the upper flange portion 33 and the lower flange portion 34 on the right side of the slider 30. In this embodiment, as Figure 5 、 Figure 6 、and Figures 12 to 14As shown, recessed portions 731 are provided on both the front and back surfaces of the half-chain teeth 73. The front recessed portion 731 of the half-chain teeth 73 can abut against the front end portion of the upper flange portion 33 on the right side of the slider 30 and receive the front end portion of the upper flange portion 33. The back recessed portion 731 of the half-chain teeth 73 can abut against the end portion of the lower flange portion 34 on the right side of the slider 30 and receive the front end portion of the lower flange portion 34, thereby better restricting the insertion rod member 70 from idling towards the disengagement side and better guiding the insertion rod member 70 to rotate towards the engagement side.
[0099] Furthermore, as Figure 15 shown, the outer peripheral contour of the recessed portion 731 includes a plurality of recessed inclined surfaces 75. The plurality of recessed inclined surfaces 75 are sequentially connected from back to front along the length direction of the zipper, so that the recessed portion 731 receives the front end portion of the upper flange portion 33 and / or the lower flange portion 34 with a surface, and better restricts the insertion rod member 70 from rotating in the direction of disengagement.
[0100] Furthermore, as Figure 15 shown, the inclination angles of the plurality of recessed inclined surfaces 75 are different. Specifically, the slopes of the plurality of recessed inclined surfaces 75 with respect to the central axis (i.e., the above-mentioned first central axis S) extending along the length direction of the zipper gradually increase. In this embodiment, there are three recessed inclined surfaces 75, and the three recessed inclined surfaces 75 are respectively the first inclined surface 751, the second inclined surface 752, and the third inclined surface 753 that are sequentially connected from back to front along the length direction of the zipper. Both between the first inclined surface 751 and the outer peripheral surface of the half-chain teeth 73 and between the third inclined surface 753 and the outer peripheral surface of the half-chain teeth 73 are connected by an arc segment 754. Thus, the angle between the first inclined surface 751 and the first central axis S < the angle between the second inclined surface 752 and the first central axis S < the angle between the third inclined surface 753 and the first central axis S, and the third inclined surface 753 is the steepest with respect to the first central axis S extending back and forth. When the front end portions of the upper flange portion 33 and the lower flange portion 34 collide with the half-chain teeth 73, the first inclined surface 751 distributed on the rearmost side in the recessed portion 731 can receive the front end portions of the upper flange portion 33 and the lower flange portion 34, so that the half-chain teeth 73 do not idle, and thus the insertion rod member 70 does not idle. Due to the increase in slope of the remaining recessed inclined surfaces 75, the second inclined surface 752 and the third inclined surface 753 are distributed on the front side of the upper flange portion 33 and the lower flange portion 34 along the moving direction of the slider 30 when the zipper is closed. Then, a certain force needs to be applied by the user to the slider 30 to make the upper flange portion 33 and the lower flange portion 34 pass over the second inclined surface 752 and the third inclined surface 753 and pass through from the outer peripheral side of the half-chain teeth 73. It is precisely due to the application of this force that the insertion rod member 70 is better driven to rotate towards the seat rod member 40, and the insertion rod member 70 and the seat rod member 40 are better combined.
[0101] Furthermore, as Figure 10As shown in the figure, a reinforcing rib 35 is fixedly provided on the upper surface of the upper wing plate 31 near the right side of the plug rod member 70. The reinforcing rib 35 integrally protrudes upward from the upper surface of the front end side of the upper wing plate 31, thereby enhancing the structural strength of the upper wing plate 31.
[0102] Furthermore, the engaging manner between the seat rod member 40 and the plug rod member 70 is snap-fitting. As Figures 7 to 9 and Figures 12 to 14 shown, a snap-fitting recess 45 and a snap-fitting post portion 77 are respectively provided on the right side of the seat rod member 40 and the right side of the plug rod member 70. The snap-fitting recess 45 can accommodate the snap-fitting post portion 77. Based on this, a snap-fitting recess 45 can be provided on the right side of the seat rod member 40 and a snap-fitting post portion 77 can be provided on the left side of the plug rod member 70; alternatively, a snap-fitting post portion 77 can be provided on the right side of the seat rod member 40 and a snap-fitting recess 45 can be provided on the left side of the plug rod member 70. Whether the snap-fitting recess 45 is provided on the seat rod member 40 or the snap-fitting recess 45 is provided on the plug rod member 70, an inclined protrusion 421 that can drive the slider 30 to incline to the right is provided on the seat rod member 40 on the same side as the slider 30 is distributed. In this embodiment, as Figures 7 to 9 and Figures 12 to 14 shown, a snap-fitting recess 45 is provided on the seat rod member 40 and a snap-fitting post portion 77 is provided on the plug rod member 70. The following description will be given based on this setting structure.
[0103] In the seat rod member 40, as Figures 7 to 9 shown, the seat rod member 40 further includes a seat rod column portion 46 integrally extending forward from the front end of the seat rod main body portion 41, and an upper snap-fitting arm 47 and a lower snap-fitting arm 48 both extending rightward from the right side of the seat rod column portion 46; the seat rod arm portion 42 is distributed on the left side of the seat rod column portion 46, and a flange receiving groove 49 is formed therebetween; the upper snap-fitting arm 47 and the lower snap-fitting arm 48 are distributed vertically opposite to each other, and a region with an opening facing right formed between the seat rod column portion 46, the upper snap-fitting arm 47 and the lower snap-fitting arm 48 constitutes the snap-fitting recess 45. The seat rod member 40 is injection-molded and fixed at the lower end of the right side of the first tape 10, and the seat rod main body portion 41, the seat rod arm portion 42 and the seat rod column portion 46 are injection-molded on both the front and back surfaces of the first tape 10. When the seat rod member 40 and the plug rod member 70 are combined and the slider 30 is located in the slider receiving area 80 and abuts against the seat rod main body portion 41, as Figure 5 and Figure 6 shown, the gap 43 formed between the portion of the seat rod arm portion 42 other than the inclined protrusion 421 and the slider 30 is the left portion of the flange receiving groove 49, the upper flange portion 33 and the lower flange portion 34 on the left side of the slider 30 are both located in the flange receiving groove 49, the seat rod column portion 46, the upper snap-fitting arm 47 and the lower snap-fitting arm 48 are all located in the chain tooth guiding path 39 of the slider 30, and the front end of the snap-fitting recess 45 extends to the rear side of the connecting column portion 36 in the slider 30.
[0104] In the plug member 70, as Figures 12 to 14 shown, the engaging post portion 77 extends integrally forward from the front end of the plug main body portion 71. The front end of the engaging post portion 77 and the half chain tooth 73, and the right side of the engaging post portion 77 and the plug arm portion 72 are connected by the plug transition portion 78. The plug member 70 is injection-molded and fixed at the lower end of the left side of the second tape 50, and the plug main body portion 71, the plug arm portion 72, the half chain tooth 73, the engaging post portion 77, and the plug transition portion 78 are injection-molded on both the front and back surfaces of the second tape 50. When the seat rod member 40 and the plug member 70 are combined, and the slider 30 is located in the slider accommodating area 80 and abuts against the seat rod main body portion 41, as Figure 5 and Figure 6 shown, the front end of the engaging post portion 77 extends to the rear side of the connecting post portion 36 in the slider 30. The engaging post portion 77 is screwed into the chain tooth guiding passage 39 in a manner of rotating relative to the slider 30 to the left and engages with the engaging concave portion 45.
[0105] Furthermore, the rotational mating structure between the seat rod member 40 and the plug member 70 is as follows: as Figure 8 and Figure 9 shown, a rotating shaft portion 410 protruding rearward is provided on the rear end surface of the seat rod main body portion 41; as Figure 12 and Figure 13 shown, a rotating shaft hole 79 with an opening facing forward is provided on the front side of the plug main body portion 71; the rotating shaft portion 410 can be rotatably accommodated in the rotating shaft hole 79, thereby realizing the rotational mating between the seat rod member 40 and the plug member 70. Of course, in other embodiments, it may also be that a rotating shaft hole 79 is provided on the rear end surface of the seat rod main body portion 41, and a rotating shaft portion 410 protruding forward is provided on the front side of the plug main body portion 71, and the rotational mating between the seat rod member 40 and the plug member 70 is realized through the rotational mating between the rotating shaft portion 410 and the rotating shaft hole 79.
[0106] Furthermore, the separable insert formed by the seat rod member 40 and the plug member 70 is a magnetic member structure. Specifically, as Figure 2As shown, the seat bar component 40 further includes a first magnet 44 fixed in the seat bar main body 41, and the first magnet 44 is preferably fixed in the rotating shaft portion 410; the inserting bar component 70 further includes a second magnet 76 fixed in the inserting bar main body 71, and a magnetic adsorption force that causes the seat bar component 40 and the inserting bar component 70 to rotate towards each other can be generated between the first magnet 44 and the second magnet 76. By using the magnetic adsorption force generated between the first magnet 44 and the second magnet 76, the seat bar component 40 and the inserting bar component 70 can be better rotated towards the combining direction, so that the left side of the inserting bar component 70 can be more firmly rotated and inserted into the slider 30, avoiding the separation of the combination of the seat bar component 40 and the inserting bar component 70, and thus more reliably avoiding idling; at the same time, it is also convenient for the rotational combination of the seat bar component 40 and the inserting bar component 70, improving the operability at the beginning of zipper closing, and ultimately enhancing the user experience.
[0107] Furthermore, as Figure 8 and Figure 9 shown, a limiting abutting portion 411 protruding backward is integrally provided on the rear surface of the seat bar main body 41, and the limiting abutting portion 411 is distributed on the front side of the rotating shaft portion 410. The front end of the limiting abutting portion 411 is connected to the rear end of the lower engaging arm 48, and the left end of the limiting abutting portion 411 is connected to the right side of the rear end of the seat bar arm portion 42. The front surface of the limiting abutting portion 411 is an abutting inclined surface 412, and the abutting inclined surface 412 constitutes a part of the outer peripheral wall of the slider accommodating area 80; when the slider 30 is located in the slider accommodating area 80 and abuts against the seat bar main body 41, as Figure 6 shown, the rear end surface of the slider 30 just abuts against the abutting inclined surface 412 of the limiting abutting portion 411, and the two are in surface contact and fit, and the limiting abutting portion 411 plays a certain limiting role in pulling the slider 30 backward into the slider accommodating area 80. In particular, as Figure 6 shown, the inclination angle of the abutting inclined surface 412 with respect to the central axis extending in the zipper width direction is β, and the inclination angle β of the abutting inclined surface 412 is the same as the inclination angle α of the inclined protrusion 421 that drives the slider 30 to incline towards the inserting bar component 70, better guiding the slider 30 to incline towards the inserting bar component 70 at the beginning of closing the zipper.
